Spccication forming part of Letters Patent No.-207,251, dated August 20, 1878 5 application filed Angust, 1878. c

To all whom it may concern:

i l others skilled in the art to which it appertains c to make andnse the same, reference being had to the accompanying drawings', and to letters of reference marked thereon, which form a part c of this'speciiication, in which- I Figure l is an enlarged. top-plan view of partslshown at Fig. 3. Fig. 2 is a sectional -viewinthe line in Fig.4 1. Fig. 3-isa'perspective view of a construction embodying our c invention, partly broken away to diminish the surface covered by the drawing.

Our mvention relates toV devices for actuat- .ing the seeding mechanism of corn-planters,

and specially to thatV class of devices which are seated on the corn-planting machine as attachments, and are adapted to beoperated by a knotted` check-rowwire or eord';` and the inventionuconsists' in combining` with a pinion and the devices actuated thereby, a segmental gear, for giving' an. oscillating motion to the pinion, and constructed to-fact as a stop at the end of each throw of the pinion.

j i The invention also consists in arranging the oscillating pinion relatively with the seedslidesV and connecting-rod therewith, in such mannerthat the connectingrod will be over or nearly over the center of the pinion at the end? 012i each'- throw of the slides, and will preventany accidental. jar from operating the slides.l

The invention also consists in constructions and combinations hereinafter described `and claimed. f f

Referring Vto the Vdrawings by letters, letter A represents a-'transverse bar, with head-bars I 1B Bon each end, having guide-pulleys C on threriront endsand' gnidepulleys Don their "rearends, anda rock-shaft, E, with forked lever c opone end, and another, e', on itslother end.

Fris ai stretched knotted wire or cord for actxating the rock-shaftE in one direction by :contact withal-he forked levers e c', and F is a spring which gives it the necessary return movement.

The foregoing parts are of common and ordinary construction and operation, and need not be further described here.

The rear pulleys, D, have each an arm, d, projecting upward on its inner side, to prevent lateral displacement in that direction of the cord or wire F, and an arm,pd, projecting rearward at an incline, and provided with a pulley, d, which retains the cord or wire upon the pulley D, and prevents lateral displacement in the direction opposite from the arm d.

G is a plate afiixed to the bar A, and has cam-tracks H at its front end, and a stud, g, at its rear end, on which is journaled a bar, l, carrying pawls J J, the forward ends of which have guard-arms j to keep them in place on the vcam-tracks H, and cams g to properly elevate the pawls in passing each other. The parts described in this paragraph are same as the similar part-s 'described infpatent to Jas. Bering and A. and M. Barnes, No. 197,818, except that the cam-tracks H have not any shoulders if? and the bar I has not anyarn1 e, 'as described in said patent, and the barI has `in our improved device a segment-gear, I', on

oneend. The pawls J receive motion alternately from a tappet, K, on the rock-shaft E, and thus impart an'oscillating movement to the bar I, Same" as Vin'aioresaid patentyand `therefore not needing description here.

,L is a pinion, journaled ou a stud, l, which projects upward from-the plate'Gr. The pinion L gears with the segment-gear I', and has a wrist-pin, l', from wliiclf a connecting-rod, M, extends to the upper `end of a 1eve`r,`-N, which is fulcrnmed-at-its midlength tothe bar A, and the lower end'of which may be connected to the ordinary bar which connects the seed- Slides of a corn-planter, and by which they are operated. y

It will be Seen that the oscillating motion of the roclrshaft E will impart alternate reciproeatin g movement to the pawls J, and thus oscillate or vibrate thelsegment-gear I, which will in turn imparta rocking` or reciprocating rotary movement to the pinion L, and thus give the necessary oscillating movement t0 the lever N by means o f the connecting-rod M.

tive positions of the connecting-rod M and pinion L.(vthe rod M onor near the center of the pinion) will prevent a movement in the other direction, except it 4comes through a movement of the segment-gear I', and thus prevent any sudden jars of the corn-planter or other causes from moving the seed-slides.

It will 'readily be seen that the pinion L may have a limited number of teeth as ian equivalent stop device for the limited number in the segment-gear I.

Having thus desclibed our invention, what We claim as new, and desire to secure by Letters Patent, is-- l. In a check-row attachment for corn-planters, a segment-gear, l', constructed with. its ends adapted to act as stops for the pinion L, in combination with said pinion and rod M, whereby said pinion is revolved half a revolution at each throw, substantially as described, and for the purpose specified.

2. The rock-shaft E, tappet K, and pawls J and its ends thus bev J, in combination with the segment-gear I', pinion L, and connecting-rod M, substantially asdescribed, and for the purpose set forth.

3. In a check-row attachment to corn-planters, an oscillating pinion, L, and rod- M, for .v

las and for the purpose specied.

4. In' a check-row attachment to corn-planters, an oscillating pinion, L, and rod M, for actuating the seed-slides, relatively arranged .as described, in combination with a segmentgear, I', substantially as and for the purpose y specified.

In testimony that we claim the foregoing as our own we affix our signatures in presence of two witnesses'.
